Sugar free Cupcake Recipe

Before I share this tender cupcake with you, I want to let you know right away that this is a sugar free dessert and lower carb than a traditional cupcake, but it is not Keto.

There are some days I really crave the tender crumb from cakes and cupcakes that only flour can give us.

Luckily, I don’t have food allergies that prohibits me from occasionally enjoying gluten in my diet. I try to limit my carbs in other ways without compromising the taste and flavor of a recipe.

In this case, I used cake flour, which is a fine flour. Although, unlike a traditional vanilla cupcake recipe, I replaced granulated sugar with monk fruit.

It’s kind of the best of both worlds. A little healthier dessert, but still delicious and fit for any special occasion.

Make these sugar free cupcakes for your next birthday celebration! I guarantee that no one will know that it’s sugar free!

Don’t be intimidated by the ingredient list. Although, it’s a little more work than opening a box of pre-mixed cake, you’ll find the ingredients are stocked pantry items.

Sugar Free vanilla cupcakes

  • Cake flour or all-purpose flour
  • Baking powder, baking soda, salt
  • Butter, unsalted
  • Sugar free sweetener (granulated) – I use Lakanto (affiliate) monk fruit
  • Vanilla extract – Have you make your own yet? Do it!
  • Eggs
  • Oil – canola, vegetable
  • Buttermilk
  • Fruit puree and fresh fruit (I used strawberries) to fold in the batter (optional)

For strawberry flavored cupcakes

You can also add any fruit to the batter. My favorite is sugar free strawberry puree or how about cherry compote? Add into the batter and frosting as noted in the recipe card.

How to make vanilla cupcakes

These delicious vanilla cupcakes will be your go to cupcakes because there are so many ways to enjoy them.

In fact, by dividing the batter in half, you can make some cupcakes plain vanilla, and the remaining flavor with a puree folded into the batter.

Lot’s of delicious ways to fit your occasion.

  1. Whisk together flour, baking soda, baking powder, and salt.
  2. In a separate bowl beat the eggs until light and frothy. Gradually add the sweetener, the the oil, and vanilla.
  3. Alternate adding the flour and buttermilk into the egg mixture. First add the flour, then add half of the buttermilk. Repeat ending with the flour.
  4. At this point add in additional flavors into the batter or bake the vanilla cupcakes plain.
  5. Bake and let col completely before adding frosting.

Additional sugar free frostings

Keep the cupcakes plain or add a frosting of your choice.

Do I have to use cake flour in this sugar free cupcake recipe?

No. If you don’t have cake flour stocked you can use all-purpose flour in the same amount as a replacement.

Cake flour adds tenderness to the cupcake, so just be aware that your cupcake will be slightly denser.

Can I use frozen fruits?

If you decide to fold in strawberries or any other fruit into the vanilla cupcake, I don’t recommend using frozen fruits for this recipe. The water may alter the cake batter texture.

The cupcakes will still taste delicious, but may not be light and fluffy with the extra liquid from the frozen fruit or berries.

How to store cupcakes

Too many cupcakes to enjoy right away? No problem. These can be left on the counter top for a couple of days at room temperature.


Place cupcakes in an airtight container and keep in the refrigerator for about 1 week.


Alternatively, you can place cupcakes in an airtight container in the freezer for up to three months.

Unfrosted cupcakes can be individually wrapped in saran wrap before placing in an freezer bag or airtight container.

I like to use a freezable plastic container so the cupcakes keep their shape, and don’t get squished by the foods in the freezer.

Frosted cupcakes can also be frozen. Just be sure to use an appropriate size container. Defrost on the counter or the refrigerator before enjoying.

  1. I think I filled mine too full, so then the middle was still goey, so I cooked them longer, and they ended up dry!
    This was the test run, so next week for the birthday party I will bake for less time!

  2. Would Love to try I will have to use gluten-free flour I am lactose intolerant. What can I use instead of the buttermilk thank you so much.

  3. The ingredients list says I need unsalted butter, but then the recipe has no butter in it. Do I need butter?

  4. Hi I followed this recipe to a T and it said it would be thin, and it wasn’t it was very thick. Would that be because I substituted all purpose flour for gluten-free flour?

  5. Why is the nutritional info saying such high sugar when these are sugar-free cupcakes? Are these not sugar-free?

    1. Hi Krista, The macronutrients are automatically pulled from a database and sometimes it gets the information wrong. You can use a different recipe analyzer like VeryWell or My Fitness Pal, which I recommend due to individual nutritional needs. Monk Fruit won’t have the impact like sugar does. Hope this helps!

  6. How would this bake up as a cake? I have an order for a sugar free cake and I’m struggling to find a good recipe

    1. Hi Alexis! Yes, can can use this same recipe to make a cake. You will grease and flour two 8″ cake pans. Same temperature as the cupcakes for about 25 minutes. Good luck!
